Project Description Solar Operated Grass Cutter Bot Our project is a battery powered automatic
Grass cutter. Initially the user will control the Grass cutter
along a desired path and the mower will record the movements in order to later replicate them autonomously through AVR Programming.
It will have a solar powered charging station that will act as the starting and ending point of the moving and cutting process.

Function List Grass Cutter will have the ability to be controlled
Automatically. It will be able to store the desired moving path in
memory It will have wheels that control forward and backward
movement as well as turning Interaction between mower, Solar station, and control
unit Solar power to large battery to mower batteries Automatic shut-off if it tips over. Micro-controller to interact with and control other
components (motors for blades/wheels, Solar component, and power management circuit.)

Possible Extra Features• Integrated scheduling of mower.• Disable the mower if it leaves its
designated mowing area.• Automatic moving and turning through the
500ms delay given.• The regulation of AVR voltage through
7805 voltage Regulator.

Feasibility Our members consist of three EE students. We have previous experience with
microcontrollers and moving of robot with sensors and motor drivers from prior Projects.
Sound programming experience. Possible outsourcing of chassis construction
and mechanical functionality

More In-depth Look

System Implementation AVR will be the communication protocol used
by Programming . Two L293D motor drivers for controlling
wheels movement and turning. Battery voltages will be monitored using the
UPS converters via solar plates into the microcontroller and motor drivers.
Switches for set and Reset of system.

Risks Mechanical issues (motor mounting, frame
retrofit) – enlist mechanical major’s help. Motor issues (possible magnetic interference,
excessive power consumption) – might need to shield motors, use smaller motors and lighter frame.
Extra supply of current more than 1.5 m amp.
Shorting of battery and solar panel wires. Bot size to inherit Turning Issues.
